Glacier Bay is the end result of the Little Ice Age which reached its maximum advance in about 1750. Today you must travel 65 miles from Juneau to Glacier Bay to view tidewater glaciers. Park Headquarters is at Bartlett Cove where additional information is available.
Park Rangers board Cruise ships traveling up the bay, their presentation is well worth attending. Information they provide will assist you in answering the questions posed as logging requirements.
Reid Glacier sits inside Galcier Bay National Park, sharing a large icefield Lamplugh and Brady galciers. It extends from the Brady Icefield between Mt Bertha (10204 feet/3110m) and July Fourth Mountain (5007 feet/1526m). It trends north 11 miles from the Brady Icefield and meets Glacier Bay south of Russell Island.
Named for Harry Fielding Reid, 1859-1943, geologist and professor at the Case School of Applied Sciences and Johns Hopkins University, who visited Glacier Bay in 1890 and 1892, and made a study of the glaciers in the area. He was one of the first scientists to study how glaciers move. For more on glacial movement, HOW GLACIERS MOVE (US National Park Service)
Glaciers move by internal deformation of the ice, and by sliding over the rocks and sediments at the base. Internal deformation occurs when the weight and mass of a glacier causes it to spread out due to gravity. Under the pressure of its own weight and the forces of gravity, a glacier will begin to move, or flow, outwards and downwards. Valley glaciers flow down valleys, and continental ice sheets flow outward in all directions.  The sheer weight of a thick layer of ice, or the force of gravity on the ice mass, causes glaciers to flow very slowly.
Ice is a soft material, in comparison to rock, and is much more easily deformed by this relentless pressure of its own weight. Ice may flow down mountain valleys; fan out across plains, or in some locations, spread out onto the sea. Movement along the underside of a glacier is slower than movement at the top due to the friction with the underlying ground's surface. Where the base of the glacier is very cold, the movement at the bottom can be a tiny fraction of the speed of flow at the surface.
Glaciers move because there are many layers of a glacier, and once the solid ice has become compressed enough, it turns into a flowy solid. This flowy solid is called plastic flow, and causes basal slipping of the glacier. The water lubricates the glacier so that it can move.
Sliding occurs when the glacier slides on a thin layer of water at the bottom of the glacier. This water may come from glacial melting due to the pressure of the overlying ice or from water that has worked its way through cracks in the glacier. Glaciers can also readily slide on a soft sediment bed that has some water in it. This is known as basal sliding and may account for most of the movement of thin, cold glaciers on steep slopes or only 10 to 20 percent of the movement of warm, thick glaciers lying on gentle slopes.
1) Identify the weather conditions on the date of your glacier visit.
2) Who named this glacier and what year was it named?
3) At the time of your visit, is Reid Glacier receding, advancing or stable? Briefly explain the reason(s) for your answer.
4) Since Prof. Reid studied glacier movement; Identify two or more means of glacier movement. Can you observe any evidence at this location that reveals this movement?
Additional but not a requirement:
post a photo of Reid Glacier with your GPSr or a photo of the glacier taken from your ship showing you or a portion of the ship in the photo.
